The regular Efiling PIN is 5 digits and will be encountered during the process of efiling.

If you have a 6-digit IP PIN to enter, here's where to enter it.

·         FEDERAL TAXES tab. (or Personal tab in Home and Business)

·         Then sub tab "Other Tax Situations."

·         Scroll down to "Other Return Info".

·         Find subtopic "Identity Protection PIN", and click START.

Do we do this for each family member who has an IP PIN including dependents?

ALL IP PINS  for everyone listed on the return are entered in the same place ... always has and always will ...
